Phone Case material comparison among PC TPU silicone

With the rapid development of science and technology level, mobile phone beauty industry as a new born ushers in a potential future. Fashion IT brand follows the diversification of the market development. For the increase in mobile phone brands and functions related accessories were also diversified. Such as the one of most phone accessories phone case on materials includes PC, leather, and silicone, TPU, fabric, hard plastic, leather, metal tempered glass shell, soft plastic, velvet, silk and other categories. The Mobile phone shell not only as an ornament to make your phone a landscape, more able to protect mobile phones from drop, scratch, water and shock. Next Cell Phone Age com will talk about several materials’ advantages and disadvantages.

Silicone

Advantages: cheap, high adsorption performance, good buffer performance, easy to wear, more comprehensive protection. Disadvantages: texture thicker, less style, easy to greasy, and the body fit slightly worse, while the material is also slightly easy to stick ash and into the gray.

Different flexibility: silicone material protective cover is generally soft texture, good pull; feel slightly slippery, if the silicone inside the high pull material to add too little, then it is easy to be pulled off, how to know its high pull it? Hand the amount of light to pull the product, if the product has a white phenomenon, then the high tension is too small, if forced to pull a little white or no white phenomenon is qualified products.

Different molding processes:

Silicone molding process is the use of vulcanization molding; this process is the use of hydraulic pressure and pressure, with the mold to vulcanize the product out. This process is relatively low cost, high yield, the application is more common. It is used for monochrome silicone products. Can also be applied to two-color double hardness of the product or multi-color multi-hardness, but the product structure is not flexible, limited. Silicone mold is a mold from top to bottom; put a piece of silicone material cut, placed inside the mold, heating and pressure to make the product.

TPU

Advantages: high wear resistance, high strength, cold resistance, oil, water, resistant mold, good flexibility. Disadvantages: easy to deformation, easy to turn yellow.

TPU soft and hard characteristics between the rubber and plastic, TPU hardness range is quite wide, by changing the TPU reaction components of the ratio, you can get different hardness of the product and with the increase in hardness, and its products remain good Elasticity and abrasion resistance. Well-known abrasion resistance, tear resistance, and creep strength are excellent; high tensile strength, elongation, long-term compression and low permanent deformation rate are the significant advantages of TPU.

TPU is a plastic category, the product is injected into the molding process to do is to put a grain of plastic rice heating after melting, with a barrel into the plastic mold and made of products. TPU can be done that kind of transparent, the most permeable are very hazy like a thick fog that feeling. It is because of this transparent feeling TPU, now more popular with users. And TPU products are still a lot of high-grade, selectivity is relatively strong, pattern changes are more.

PC

Advantages: good light transmission, hardness, anti-fall, thin, good strength and toughness. Disadvantages: no anti-scraping, intolerant strong acid, intolerant alkali, impatient UV.

PC (polycarbonate) itself is a tough thermoplastic resin, PC material impact resistance, strength and toughness is very good, whether it is heavy or normal beat, as long as you are not trying to hit it with a stone, it is enough Longevity, while transparency is also high but its appearance is easier to scratch.

PC material for phone case has three kinds of technology: vacuum plating process: in the PC shell plating, electroplating finished carving some patterns, texture is good, but after a vacuum plating to a UV varnish. PC spray technology: you can spray the sense of rubber oil, this feel there are a lot of people like, and then the complex is in the colored (transparent red, transparent blue, transparent yellow, etc.) transparent PC shell spray a layer of primer, and then laser engraving some patterns , And finally had a rubber paint, this product is very upscale. PC water transfer thermal transfer process: PC shell to do some transfer up the pattern, and then spray UV varnish, or soft feel rubber oil. After the transfer of UV Varnish, hand pinching, the surface of the UV varnish is easier to split, so the best choice for the transfer process spray rubber oil, soft feel, the surface matte, do a good process , Will appear very upscale. The disadvantage is that the surface is not resistant to scraping, if a local out of the paint, the splash will go down the paint where it is easy to get off more and more. Transfer the advantages of pattern is very rich color.

With the users taste more and more critical, many mobile phone parts manufacturers have begun to make innovation on protective case material began to use composite materials to produce phone case. But on the whole, the physical properties of TPU material are relatively more prominent. But each kind of protective phone case also has its own advantages. TPU main features are low viscosity, good resistance to flexing, excellent wear resistance and high gloss. At present the new arrival TPU Protection Phone Case for iPhone 7 is only 12USD including shipping from Cell Phone Age com.
